Where large faucets or valves are used withcorrespondingly large plungers it is desirable to provide ducts orpassageways 23 through the plungersi to facilitate the flow of liquid tofill the I space 25that is created by depression of the plunger. Theseducts may be formed relatively large, and various sized bushings orreducing elements 2!? adjustably threaded therein to provide forvarying" dimensions to govern theflow of liquid to and fro therethrough.The return or upward movement o-f the plunger, after the rod above isreleased, is controlled and the time of closing of the valve determinedby return or down flow of the accumulated liquid from the spaces 25. g r

have found that only a small space is there required to provide adesirable flow of water both from the nozzle and up above the plunger,all under ordinary city water pressure. My faucet is specially valuablefor preventing loss of water where m'generaluse by the public, whenfaucets may be left open carelessly. The device may be also adapted fornumerous other uses, as for regulated or measured flow when desired, and[or flushoineters or toilet tanks, etc. The valve may be opened byvarious means (not shown), as by soleno-id or electrical or othermechanical means, or byifioats in water tanks, etc. My faucet ispreferably formed entirely of metal,
